Here is a player of of music files which can deal with big file collections quickly and guarantees to play each track only once, even in shuffle mode, before any track gets repeated. A lot of work was put into playlists, so that they can be easily generated and managed. It can play any file format Windows knows to play.

You can use it out of the box, or, if you are like me, you can add features as you please. It is completely written in C# using WPF.

The main screen shows the playlists on the left and the items of the selected Oldies playlist on the right. At the bottom are the buttons to play, pause, skip to next track and shuffle mode. By the way, if you don't like the looks of the user interface, you can easily change it, it is all WPF.

There are different windows for importing tracks, managing all tracks or just managing a single playlist. They all display the tracks in a DataGrid, which gives great flexibility to search, sort and filter them.

The user can search for any text in track title, album name, composer, publisher, genre, year and hard disk folder. All this information is stored in the track files themselves, which is kind of cumbersome to edit in Windows File Explorere. The MusicPlayer supports changing them directly in the application.

Information about the tracks, playlists, etc. are stored in CSV files on the local hard disk using my library StorageLib. It is a replacement for a database with the advantages:

• Just define your classes and their properties, StorageLib will create all the code needed for storing the data permanently
• Support for hierarchical data structures, guaranteeing the data integrity (no child without a parent).
• Transaction support
• Automatic backup
• all data stored in RAM, resulting in extremly fast data access using LINQ.

1. Get https://github.com/PeterHuberSg/StorageLib. This is the library used to store data on the local hard disk.

2. Get the code of https://github.com/PeterHuberSg/MusicPlayer. Its parent directory should be the same as the parent directory of StorageLib.

3. Install the nuget packages:
   Ookii.Dialogs.Wpf
   TagLibSharp

To run the application start MainWindow in the MusicPlayer project. Once Musicplayer starts, it will ask you in which directory it should store its data, then it shows a help screen explaining the next steps.

Contains the WPF application, which starts with MainWindow. MainWindow.xaml.cs starts the data Layer MusicPlayerCore.

MusicPlayerCore contains all the auto generated classes with names like xxx.base.cs. They contain classes for Tracks, Playlists, PlaylistTracks, etc. The developer can add functionality to the auto created classes by adding a xxx.cs file.

DC.base.cs is the data context and gives static access to all data like this: DC.Data.Xxxs

MusicModel contains the data model. In there I have defined classes like Track and all its properties. StorageLib then created the classes like Track.base.cs. Each time an instance of Track gets created, updated or deleted, a copy gets maintained in the Track.CSV file. On startup of MusicPlayer, these .CSV files get read and all the data made available in Ram, like DC.Data.Tracks.
